Trail Dust Town has been a Tucson landmark for half a century. It houses antiques shops, an old-fashioned candy store, restaurants and a saloon where you can belly up to the bar and have a frosty mug of draft root beer. Test your skills at the shooting gallery or ride the train, carousel or Ferris wheel. Have a hearty meal at Pinnacle Peak Steakhouse.

Here's a sweet way to cool off this summer. Drive the Catalina Highway near Tucson from the desert floor to ponderosa-pine forest. The twisty drive takes at least 45 minutes, and there plenty of scenic places to stop and enjoy the view. Once you reach the tiny community of Summerhaven, treat yourself to decadent homemade fudge at Mount Lemmon General Store. But keep your hands off the Heath English toffee and mocha fudge flavors — they're mine.

A little over a week ago, we were filming at the South Rim of Grand Canyon. While we were there, 100 APS volunteers were working with a hot-shot team to clear brush and other flammable debris in advance of wildfire season. We spoke with park superintendent David Uberuaga, who told us how important volunteers are to national parks. Volunteers can help in many ways, from cleaning up to working in the library. Julie Coleman, executive director of the APS Foundation and corporate-giving manager at APS, explained why the volunteers were helping out: "The Grand Canyon is a crown jewel that's in our backyard, and as one of the leading corporate citizens, APS and their employees consider it both a responsibility and a tremendous privilege to give back and to invest."
